To all whom it may] concern.' l

Be it known that I, HARRY H. STYLL, a citizen of the United States, residing' at Southbridge, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Oph-e thalmic Mountings, of Vwhich the following is a specification. l

This invention relates` to ophthalmic mountings andhas particular reference to improvements in lens engaging membersor clips. c Y The primary object of the invention is to provide an adjustable clip of this character', whereby 'it' may be readily and easily applied to lenses having varying curves and thick nesses.` Another object of the invention is to pro'- viyde a clip of this character which will 'be positively held against accidental looseningy fromy the lens in contraedistinction to being merely secured thereto through the medium of the adhesive properties of the cement or other uniting material. Y j

A further object of the invention is to provide an adjustable clip of this character in which the ears Willfirmly engage with the lens vthroughout their lens engaging area, irrespective of the curve or. thickness of the lens", thereby providing for a iirm, secure and etticientconnection between therlens and clip, and providing amounting which is neat inappearance.

a San further Object @fl theinjve'ntion is t0- provide a novel form of lens, when the saineis of greater thicknessthan the maximum adjustedwidth of the clip, whereby the clip may be readily applied thereto. Y c

Vith the foregoing, the invention consists in the novel features of construction, combination and arrangements of art's,'as willbev hereinafter more fullydescribed, illustrated inthe laccompanying drawings and claimed.

showing the same as applied to a lensas illustrated lnFig. II of the drawing. 'Fig VIII 1s a detailed "perspective view vof the clip" shown in' Figs. III andVII of'the drawing.

F ig. IX is a view similar to Fig. IV, showing the application of this form of clip to another form of my improved lens.l Fig. X isa horizontal sectional view taken centrally through another modified form of clip; Fig. XIis a sectional view of still another modified form of'clip. Referring to the drawings by numerals, 1

designates a lens which may be of any thickness,'and which may be ground to any desired curve, while 2 designatesa Aclip for attachment thereto. i

As previously mentioned `it' is they objectt of the invention to enable a cementitiously fastened lens clip to be Vapplied to a lens irrespective of fthe thickness or curve of the.' lens. In Figs. I to X inclusive, and in Fig] XI ofthe drawings Ihave` illustrated at least'one ofthe `ears 'of the clip as being adjustable relativeto the-remaining ear, and

have shownV the ears as being connected by an extensible or compressible web, but in some instances, as inFigs. IILVI, and X, I have shown boththe ears as being adjustable. The cl1p is adapted to be applied to a. lens having a slot formed Iin one edge thereof to receive Vthe web, and the same is preferably secured tothe lens through the mediumof a suitable cement, or like material, and-theears of the-` clipk may be made adjustable to/permit of theirv application to lenses having varying curves and thicknesses. By the use of a construction such as has been referredfto it willv f irrespective of thefcur've ground thereon. jy f l 4Inl'Tigs(I,III and VIII of the drawinigsI have shown1 one preferred embodiment ofmyinventio11f,`*injwhich` the clip 2y comprises a strap portion' 3, ears 4c and a pair yof adjustablefweb portions l" ,"g-ilotsv .6 being formed in the strap 3., so that the ears may be readily forcedapartftopermit ofthe clip bein'g'ape plidgto lenses having thick edges'.Y f'lhe lens Y tojw'h-ich this clip isto be 'applied-.has a slot li 7; to receive the web fandfthe uniting medium, suchl as, @ement or-.ae like. Ii wi11.;be,nofed; thatrfshouldtheilens be of aconcave-or conf vex form, or in fact, any curve whatever, the

. edfor i In Fig. Y ,Y i n 'clip illustrated is substantially the same as that shown 4in Fig.. IV7 with thecxception j trated"substantially` the same construction asV set forth in connection with the showingin Fig. III of thefdrawing, but in this instance Ij haye provided `onefofthe ears rigldiwith Vthestrap portion, and have Amade the other ear adjustable.y `This clip is-,especially adaptuse upon. lenses y .havingfone plane surface. j j Y i c l of the drawingsthe form of the that instead of providinga pairs-of adjust-4 able connecting webs for ythe fears, v but 'a single web is provided, which extends` diag'- onally across the intervening space' between Y the ears and Vis adapted to bcladjusted-in a. manner similar tortliejadjustmentof the webs shown infFigs IIIfand IVloi the drawing.

In Fig. VI, I have illustrated another emibodimentof my invention, in which the ears 41 a'rebothm'ade adjustablerelative tothe strap portion by,forming{these` ears separately-from the strap portion and V:connect-y ing thesame withthe strap by meansjof the webi8andif-desireda second .web 9 may bel s Iand prevent? their` 35 provided in order to firmly connect the lsame i accidental loosening from the lens. Y

` One important advantage gained by ythe, structures and mode of fastening just de-4 scribed is'thatthe cement is placed about the webso that the webs are embe'ddedtherein,

whereby when the same hardens it willgpre-t tent any movement ofthey web',which con--` seqvuently4 prevents any movement ofthe clipl ears,- and!l thus positiyezmeans Aare provided. or preventing accidental breaking away. of

the `clip ears, as hasheretofore been common,

groan inria. Ivgaa engraving-'aanhef cess 1 formed one face ofy therein, whiletheadjustableV clip ear is adjusted to titthe curved face of the lens, as is 'clearly shown. i a In Fig. X of the drawings the ears of the clip are shown as being Separate from the strap portion, and as heilig connected thereto by means of vthe web 12 which is formed on theV strap, and which has adjustable fingers securedto the ears, inturned flanges 13 being formed on the ears and extended over the outer faceofthe strap` in order that no Vportionof theedgeo1 the lens will be exposed when the earsare adjusted away tromeach other. f j f t In Fig. XI of the drawings I have illustrated another slightly `modified form of my invention, inwhicli one rigid clip ear is prorided which is connected to `an adjustable clip ear by means of` the angularly shaped web portion 5. `Inthis form of my invention as should be apparent by reference to Vthe drawings, when it is desired to widen the clip to receiveA a thicker lens it is merely necessaryto insert a pair of pliersin the` mounting pressing against the` central corners or points` of the diamondformedby they two cross arms or webV when tightening of the pliers will serve to force the two Vears apart in the manner of operation of a toggle joint.. ,()n the other hand,-.if itis desiredv to iit lthe strap to a thinlens, pressure on the outside of-thestrap portion will compress the webavhich'` willzthen open out into a more nearly square in place of diamond Shaped ligure.V It is to be understood that these rigid vto satisfactorily hold the, earsindesired adjusted position under `ordinary serv.- ice conditions, while permitting of manipu-i vlation of the mountingjby the use of pliers or, the, like, as `has just been described. When the mounting is actually placed in use, however, 'the celnent or other connecting' medium'liszplaced in V'position when in ai softer plastic conditiom and; as is illustrated in the j various figuresofv the drawing this.y lcement fills-:all thespace .in the slotin thel lens and surroundsthe members 5, 5f 0r the like,Vv Vand, when it has been allowed toset hardens therearonnd in` the same mannerf that concrete hardeus. around, a metal fre-f inforcement or strap, and thisl hardening serves rto secure the ears in exactly desired adjusted position, sinceto shift-.them either closer. togetherjorfarther apart it is neces-1 saryto Ycrush, the hardened cement: or connectingfmedium' 17 i Consequently the .j ears lie arerniechanically locked by this material in Y the desiredrelatively ,adjusted position irre:

spective-of the. adhesive properties of ,the i" al sticking to the falceslothemetallic: pand holdingthe parts thereof inposition. Inthisconnection particular-,attention isg` also Ainvited to .the manner -in yvhichv the strapl or clip. is, retainedjin position, in that the slotted portion of the lens presents not the smooth polished exterior surface, but a rough and porous surface into which the cement will run to a certain degree when in its heated or plastic condition and with which the cement may obtain an extremely secure hold, while the fact that this cement in a continuous body extends around and has embedded thereinthe cross pieces 5, 5 or the like firmly and securely unites the clip with the lens by the mechanical formation of the hardened connecting medium irrespective of its adhesive property, it being preferable, however, that the material have considerable adhesive properties to serve both as a binder through the apertures between the web to hold the two separated portions or opposite sides of the slot together and reinforce the same, and also to better retain the lens and clip in engagement. Especial attention is also invited to the shape of the clip ears, as is clearly illustrated in Figs. I and VIII, from v-fhich it will be noted that the strap ear is of slender outwardly convex material so shaped that the rounding of the material will cause a high light on the central portion and will to a certain degree obscure the edge portion and thus render the strap considerably less conspicuous and more ornamental in appearance than is the customary flat or similar strap now in general use.

From the foregoing it will be seen that I have provided an improved clip embodying independent and relatively adjustable ears, which clip may be advantageously secured to varying thicknesses of lenses by cement or the like, which will present an extremely neat and attractive appearance and in which the parts will be so braced and locked in the presence of the cement as to prevent any accidental shifting thereof from desired adjustable position while permitting of adjustment thereof to fit the lens in the absence of the cement or connecting medium, and it will be understood that I may make any struction shown and described within the scope of the appended claims without departing from or exceeding the spirit of my invention.

I claim:

1. A lens attachment for an ophthalmic mounting comprising a strap portion and a clip ear, and a second free, or loose clip ear unattached to the strap, and a pair of bowed web or connecting members secured to and connecting the two clip ears to permit of relative adjustment of the clip ears and of movement of the free clip ear relative to the strap by increasing or decreasing the amount of bowing of the connecting webs.

2. lens attachment for an ophthalmic mounting comprising a strap portion and a clip ear, and a second free or loose clip ear unattached to the strap and a web or connecting member rigidly secured at each end to one of the clip ears and greater in length than the direct distance between the clip ears to permit of relative adjustment of the clip ears by bending of said web member.

In a moimting of the character f described, including a pair of clip ears, a pair of bowed or bent web members rigidly secured at their ends to the clip ears to prevent rocking or twisting movement of the ears relative to the webs, said webs being adapted to engage and be locked in adjusted position by a cementitious ller, a strap member, and a neck uniting the strap member with at least one of the web members, at least one of the clip ears being free from connection with the strap member except through the medium of the neck and one of the web members just referred to.

In testimony whereof I aix my signature in the presence of two witnesses.
